Ph of activated carbon
WebJan 7, 2024 · Activated carbon is a widely used media for water and wastewater treatment. Pre-wetted carbonons meet a significant number of the concerns raised. Activated carbon with a pH greater than 7 is more likely to produce an initial effluent with a pH greater than 7. The majority of activated carbon is hydrophobic, making it difficult to wet. WebChemically activated carbons have an acid pH after activation. DESOTEC C-PURE® and C-PURE® Super are therefore post treated to obtain a pH of 3-6. Upon request, DESOTEC …
